But he insists they all need to start showing that they really want to reach the top level of the game.

Keown told Starsport: "Jack has to prove this season that he is available for selection every week, he hardly played a game last season.

"I do feel he's an outstanding player but we need to see him at his best this season.

"Theo has looked really fired up in pre-season and looks to have that pace back in his game.

"Oxlade-Chamberlain has just got to apply himself with this talent that he has."

TIME TO SHINE: Martin Keown and Arsene Wenger want to see more from Arsenal's England stars

He added: "There comes a point in your career where you are not satisfied unless you're playing football every week and these three need to show some real desire.

"You have to play football week in, week out or years go by wasted.

"It's a very short career and you want to be part of that main event and have a feeling of 'I've got nothing to lose and I have to make my mark'.

"That's the sort of attitude we want, and Arsene Wenger wants, to see from these three players."
